Temperature effect on demixing and surface properties of Sn–Zn liquid alloys

Effect of temperature on the demixing tendencies in the bulk and surface of Sn–Zn liquid alloy was studied using some statistical models. In the bulk of the Sn–Zn liquid alloy, the demixing tendencies showed a large reduction as temperature increased from 650 to 875 K. With further increase in tempe...

Description
Summary:Effect of temperature on the demixing tendencies in the bulk and surface of Sn–Zn liquid alloy was studied using some statistical models. In the bulk of the Sn–Zn liquid alloy, the demixing tendencies showed a large reduction as temperature increased from 650 to 875 K. With further increase in temperature, Sn–Zn liquid alloy slowly approaches a liquid alloy of ideal mixture of components. Our calculations also indicate that the surface tension of the alloy decreases with increase in temperature below 0.5 bulk atomic fraction of Zn. However, between 0.5 and 0.85 bulk atomic fraction of Zn, there seem to be no obvious trend.
